group of people on a rooftop, silhouetted against a blue sky with scattered white clouds. A rusty wire mesh fence runs along the edge of the roof, separating the people from the camera's view. The building below the roof is light grey, possibly white. There are a dozen or so people visible, their activities aren't clear, but they appear to be standing or sitting and observing something in the distance. A few small objects that may be lights or cameras are attached to the fence. There is no other activity visible in the video.
